Use only a good quality brake fluid meeting DOT-3 specifications.
See Figure 1
The clutch master cylinder is located at the left rear corner of the engine compartment. Check the level in the clutch master cylinder in the same manner as the brake master cylinder. The level should be kept at the MAX. mark or approximately 1/4 in. from the top of the cylinder. Use brake fluid in the clutch system. Be sure that the vehicle is on a level surface.
